Thank you Jim and Les. This is good information to work with. What do you think caused the smaller tire to loose so much traction? To much torque for the smaller tire, less contact? I am assuming these smaller tires are drag radials you tried? I'm running hankook v2 now with 1.8+ 60', so they are working well. Was looking for the lighter wheel and shorter tire to achieve a quicker 60'. I am an old school drag racer, we used to do it with taller or shorter gears.
